#2Unfortunately IPv6 adoption is not a matter of just providing access lanes to this wonderful new technology. IP permeates too much of the infrastructure, tooling, etc. How could it not? Some companies might find the cost/ROI of working around IPv4 limited address space to be less than migrating to IPv6.

#4This is an extremely US-centric article. ARIN was never in as dire straits as the other RIRs. In Europe and Asia the situation is much worse. For example, lack of IPv4 addresses delayed DigitalOcean's growth in Amsterdam, and carrier-grade NAT is already being used by some consumer ISPs in Europe and Asia.

#6For an example of a real victim, look at Qatar, a country which only has a single IP address for the entire country (everyone sits behind a NAT): https://en.wikinews.org/wiki/Qatari_proxy_IP_address_tempora... [0]
Whenever someone from Qatar decides to vandalize Wikipedia, Wikipedia is forced (temporarily) to block the entire country from accessing Wikipedia. This has an adverse impact on the rest of the country.
Non-Qatari Wikipedia users also suffer, because Wikipedia makes those blocks very temporary (since they are effectively shutting off an entire country), which makes it easy for those vandals to regain access to Wikipedia quickly.
[0] This sad state of affairs is not solely due to IPv4 (incompetent/apathetic network administrators are also at fault), but it's a contributing factor.

#8I have a friend who runs a small low-cost minecraft hosting. He stopped giving his customers dedicated IPs at all. They get a range of ports and a hostname with appropriate srv records added.
That's the other result, technical work-arounds. You can point to a particular service on a particular port with an srv record, host multiple websites on one IP, even SSL-enabled ones with SNI, etc.

#9This article is focused on the US, a country which was never really going to feel the brunt of the IPv4 crunch.

#10To me, this indicates something either broken about IPv6 or a lessened severity of the IPv4 problem: If it's better to apply bandaids to IPv4 than to roll out IPv6, then either IPv6 is not easy and flexible enough to be a viable alternative, or the problems faced by IPv4 are not as intractable as was suggested.
